Application filed September 26, 1919. Serial No. 326,443.

To all who??? it may concern:

Be it known that I, EDMUND R. N EBELING, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and Improved SeparableFastener, of which the following is a full, clear, and exactdescription.

The present invention relates to new and useful improvements inseparable fasteners,

and it" pertains more particularly to separable fasteners of thehead-and-socket type. The primary object of the present invention is toprovide means by which the head or heads may be positively locked inengagement with the socket.

A further object of the invention is to provide means by which thesliding move ment of the locking member is limited.

With the above and other objects in view, reference is had to theaccompanying drawings, in whioh Figure 1 is a view in elevation showingmy improved fastener and its application to the strap of a wrist watchor similar article of jewelry;

Fig. 2 is a horizontal sectional view thereof;

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1;

Fig. 1 is a longitudinal sectional view taken on theline 44: of Fig. 1;

Fig. 5 is a sectional view with certain of the parts removed to show theassembly of the device;

Fig. 6 is a plan view of the filling plate;

Fig. 7 is a transverse sectional view of the device with the severalparts in the locked position;

. Fig. 8 is a sectional View taken on the line 8-8 of Fig. 7.

Referring more particularly to the drawings, the reference character 10designates the socket member of my new and improved fastening, and 11represents the head 1nemher. As shown in the present instance, the

socket member is provided with two openings, each of which is adapted toreceive a separate head, in the present instance there being two heads12. I do not wish to be limited to two heads, since any number of headsmay be employed so long as the socket is provided with the proper numberof open ings to accommodate said heads.

The reference character 13 designates the housing, and said housing isprovided in its bottom wall with two openings 141, and in one of itsside walls with a rectangular opening 15. Mounted in the bottom of thehousing 13, is a filling plate 16, and said filling plate 16 is providedwith two spaced openings 17 adapted to aline with the openings 14 in thehousing 13. interposed between the openings 17, are two openings 18, thepurpose of which will be hereinafter more fully set forth.

The reference character 19 designates a guide plate, and said guideplate is provided with a rectangular cut-out portion 20, the forward endof which is provided with two oppositely disposed lugs 21. This guideplate 19 is provided with semi-circular out out portions 22, the contourof which is adapted to conform to the contour of the openings 17 and 14,and said guide plate 19 is further provided with a looped portion 23,which lies eXteriorly of the housing 13, the arms of said loop passingthrough openings 24 in the rear wall of said housing. This plate 19 isadapted to be positioned within the housing 13 after the filling plate16 has been placed therein.

The reference character 25 designates the latch which is slidablymounted within the housing and is provided with a rectangular portion ofslightly smaller dimension than the rectangular cut-out portion 20 ofthe guide plate 19. This latch member 25 is provided on its oppositesides with semicircular cut-out portions 27, which when positionedopposite to the cut-out portions 22, form therewith circular openings inalinement with the openings 17 and 14 heretofore mentioned. Centrally ofthe latch member 25 is provided an integral lug 30, and said integrallug 30 is adapted to alternately engage the openings 18 to retain thelatch either in the open or the closed position, it being shown inclosed position in Fig. After the parts have been thus far assembled, afinishing plate 32 is placed over the guide plate 19 and the latchmember 25, and'the edges of the side walls of the housing 13 are turnedover as indicated by the reference character 35 to maintain the severalparts in their operative position.

lVhen it is desired to lock the head members within the openings 17, thelatch 25 is moved until its cut-out portions 27 complete the circularopenings with the cut-out portions 22 of the guide plate 19. With theparts in this position, the head members 12 are inserted into thecircular openings, after which the latch is moved to the closedposiand-sockettype, a casing,

tion shown in Fig. 5. In this position, the latch member engagesin'notches 36 of the head members 12, to prevent further displacement ofthe circular openings.

To maintain the sliding latch member 25 in this position, the lug 30 isengaged with ,the proper opening 18, thus preventing sliding movement ofthe latch member 25. As best shown in Figs. 3 and 8, the latch mem beris provided with an operating right-angular portion 40, by means ofwhich it may be manipulated.

From the foregoing, it will be seen that the present invention providesa separable fastener of the head-andsocket type, in which the head is atall times secured against accidental displacement relative to thesocket, and, at the same time, the device is simple and' cheap tomanufacture. Furthermore, the sliding latch is limited in its movementrelative to the head member and the housing in a new and novel manner.

I claim:

1. In a separable fastener of the headand-socket type, a separate outout guide socket, a sliding memcut out guide plate and head to securethe plate carried by the ber mounted in said adapted to engage the partstogether, and integral shoulders formed on the sliding member, saidshoulders engaging the guide plate for limiting the movement of thesliding member relative to the socket. r. i

2. In a separable fastener of the head and socket type, a casing, alatch member slidingly mounted in said casing, a separate guide plateWithin the casing ing latch, and strapattaching means integral with saidguide plate, said strap attaching means lying on the exterior of saidcasing.

a. In a fastener of the head-and-socket type, a head member, the form ofa casing, a separate guideplate mounted in the casing, a filling platemounted in the casing, and a latching member adapted to engage the headof the head member, said latching member being slid- .ably mounted inthe guide plate, substan tially as described. 7

r 5. A separable fastener of the head'and socket type comprising ahousing, a filling plate mounted in said housing, a separate guide plateprovided with a cut-out por-.
